Apenas tente instalar alguns módulos mais recentes do kernel. - Eles podem vir de repositórios do Ubuntu se você ativar o repositório backport no seu sistema primeiro.
Se você estiver em Maverick instale linux-backports-modules-wireless-maverick-generic .
Se você está em Natty instale linux-backports-modules-cw-2.6.39-natty-generic .
